New Polo Bluemotion and PERSISTING PROBLEMS

I bought a new Polo BlueMotion 2012. From approximately 30 000kms onwards I started experiencing the following problems and reported it in confidence that the problems would be fixed.<br> <br> 1. Fan of vehicle starts blowing full blast even when vehicle is cold<br> 2. Engine Management light appearing along with the following symptoms - no power upon acceleration, extremely rough and abrupt idling, misfiring to the extent where the engine of the vehicle shakes<br> 3. Catalytic convertor light appearing with the same the symptoms as above.<br> 4. Heat gauge warning light comes on along with fan blasting full power (AGAIN with the exact same symptoms as mentioned above)<br> <br> Each time I reported these incidents, the vehicle would go into NTT Stellenbosch and Paarl and diagnostics were done. After work was completed (and often components replaced/fitted) the EXACT same symptoms and warning lights would come on a month or two later (sometimes even within the same week).<br> <br> All of the above was within my warranty. My warranty expired in January. Car broke down with the EXACT same symptoms JUST LASTWEEK. Now all of a sudden the injectors failed, R27000 later.<br> <br> MIS-DIAGNOSIS!!!<br> <br> I will not pay for..
